Removing bottom few layers after printing?

Hi again,

So I've finally been getting some decent Pla prints coming off, although the bottom couple of layers seem to be offset in the y axis by about 5mm. Which is covering holes that should be open.

I'm gunna hav a go at fixing the slicing software, but in the meantime, any ideas on how to remove these bottom layers?

Maybe a belt sander???

Oh if only I had the money :L I'll wait a couple of days and use the school workshops in that case.

Cheers,

Ollie

Sounds like your Y axis motor is skipping steps. Either the motor isn't getting enough current to move it at the speed you've specified (exacerbated by friction), or they're getting too much current and the driver chips are temporarily shutting down to avoid cooking themselves. If you point a fan at your electronics, you can crank up the current a bit and not have to worry about this issue.
